Step 1. Preparing To Install The CST1 Rainscreen Siding System
First things first: Proper Prior Planning Prevents Poor Performance.
Before you get started, make sure that you have either OSB exterior sheathing or Plywood exterior sheathing. The Climate-Shield system is designed to install over either of these sheathings.
The Climate-Shield system is designed to let water in and out. Make sure your exterior wall is waterproof and protected with a weather resistive barrier.

Step 2. Installing Pura NFC Trim
If your project calls for Pura NFC trim components, this is the only place you will need to use furring strips.
Installing Outside Corner Trim
Install the strips with screws and level. The furring strips must be covered with a black EPDM tape or other weather resistive barrier once it is installed.
Now that your furring strips are lined up at the corners, it’s time to install your outside corner trim.

Installing the window and door trim
A big advantage of Climate-Shield Rainscreen System over other rainscreen systems is that it does not flatten the look of your exterior. Instead it installs easily around doors and windows to define the openings.

Step 3. The Climate-Shield Starter Rail vs. the Furring Strip Method
The CSTR8 starter rail is designed for Pura installation. It 8’ long, 100% stainless steel, easy to handle and install. Once your starter rail is installed level it makes all your following courses of siding line up perfectly to the top of the wall.

Installing traditional closed joint rainscreen siding means starting with a complicated matrix of wood furring strips as the base. These furring strips have to be cut and installed one-by-one into a grid before you can attach the field siding.
The upside of furring strips is they are less costly when budgeting your initial material investment. The downside is that those savings can be quickly eaten up by the time and labor needed to cut and install so many furring strips.
The old way to install vertical rainscreen siding. A complicated and time consuming matrix of furring strips that may trap moisture behind the siding.
The problem with a complicated grid of furring strips is the corners and pockets it creates behind your siding. Rain and humidity will try to evaporate up and out through the only place it can, the top course. If moisture and humid air has no simple way to flow out the top it stays trapped against the wood strips and your building exterior wall. This causes ideal conditions for rot, mold, warping, insect damage, and other decay that everyone wants to avoid.
This project was to replace replacing traditionally installed siding with better rainscreen siding. Look what they found behind the closed joint system: Black mold, decay, and damage to the entire exterior wall!
Step 4. Install The First Course of Rainscreen Siding
Slide the first siding board into the CSTSR8 starter rail. Tap into place to make sure the board is sitting tightly on the starter rail. Make sure there is adequate spacing for movement during temperature and humidity changes. And that's it!

Step 5. Fastening the Rainscreen Clips
Here's the secret sauce, the patented CST1 Rainscreen clips.
The clips installed with one screw each and automatically create the correct rainscreen gap. The clip needs a 1mm spacer to allow for the expansion and contraction, conveniently equal to the thickness of a paperclip. The clip is then fastened with one screw.

Step 6. Adding the next courses of siding
Tap it home. Make sure your gap at the end is set properly for expansion and contractions.

Step 7. Installing the top course of siding
The top edge of the end board should be ripped to the proper dimension to fit under the soffit. The bottom edge of the board should be left intact to fit securely in the clips. The top board is pre-drilled, then fastened.
